The matrix for this specimen is a bunch of interlocking microcline crystals with aegirine, natrolite, analcime and catapleiite crystals formed in the spaces between microcline crystals. The catapleiite crystals are mostly formed on aegirine crystals, either totally or partially covering the aegirine and other minerals in the open spaces. Lots to look at!
